Properties & Relations  (4)

The Hausdorff distance between two points is equivalent to the EuclideanDistance:

The Hausdorff distance between two point sets is the maximum EuclideanDistance from any point to the other set:

The Hausdorff distance between a region and a single point is the furthest distance of the point to any point in the region:

RegionDistance can be used to find the nearest distance from a point to a region:
